Measuring 5\/8 inches in overall length and fully threaded, it uses a Torx Plus T30 drive with an 82-degree flat head profile. The alloy steel construction with black oxide finish provides solid mechanical strength while offering a degree of corrosion resistance in dry or lightly oiled environments. This fastener is installed by machinists, maintenance technicians, and mechanical assemblers who require a low-profile, high-torque-transfer fastening solution.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for applications where the fastener head must sit flush with or below the surface of the mating material. The 82-degree countersink geometry matches standard countersunk hole profiles used in precision machined parts, tooling fixtures, and general mechanical assemblies. The Torx Plus drive reduces cam-out under load compared to hex socket or Phillips drives, making it a preferred choice in production and maintenance environments. Fully threaded along its 5\/8-inch length, it provides maximum thread engagement in thin materials or blind holes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-28 UNF thread for fine-pitch engagement and vibration resistance\u003c\/li\u003e\n  \u003cli\u003e82-degree flat head seats flush in standard countersunk holes\u003c\/li\u003e\n  \u003cli\u003eTorx Plus T30 drive minimizes cam-out during installation and removal\u003c\/li\u003e\n  \u003cli\u003eFully threaded 5\/8-inch overall length for maximum thread engagement\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASME\/ANSI B18.3 and ASTM F835 fastener standards\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish for a uniform low-reflectance appearance and mild corrosion inhibition\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-dimension replacement or stock fastener for countersunk Torx Plus applications conforming to ASME\/ANSI B18.3 and ASTM F835 in inch-series 1\/4-28 UNF threaded assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a calibrated T30 Torx Plus driver or bit; do not substitute a standard Torx T30 driver, as Torx Plus lobes have a distinct geometry that may cause slippage or damage with non-matching tooling. Ensure the mating countersunk hole is machined to an 82-degree included angle to achieve proper head seating. Follow applicable torque specifications from the equipment manufacturer or applicable ASME standards for 1\/4-28 alloy steel fasteners. Black oxide finish does not provide significant corrosion protection in wet or outdoor environments; apply supplemental corrosion inhibitor if required by the application.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-28\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 5\/8 inches (overall)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: 82-degree Flat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Torx Plus\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTorx Size\u003c\/strong\u003e: T30\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Fully Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME\/ANSI B18.3; ASTM F835\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.009 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 354-2410-01\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694421213490,"sku":"354-2410-01","price":2667.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/04d2f6abec8d27c1021899c23413d82c_315bd675-1993-41f2-ad6f-470fe2b7e6eb.jpg?v=1788324360","url":"https:\/\/voomisupply.com\/products\/value-collection-354-2410-01-flat-socket-cap-screw-1-4-28","provider":"Voomi Supply","version":"1.0","type":"link"}
